If I fit a mild cam and extractors / modified exhaust to a 1988 EA 3.9 mpi S-pack, or do any other mechanical mods, will the electronic management systems allow me the full benefit of the mods or will they tend to pull things back to base levels preset in the computer?
If the ECU etc will interfere with the mods, is there any way to get the maximum benefit apart from a programmable add-on to the ECU, and preferably a lot cheaper?
I understand the general idea of engine management systems, but I haven't got a clue about the details and how they interact with modifications.
